LATEST NEWS

06.12.25 - SAGE III/ISS Data Assimilation System Effective In Reducing Stratospheric Observational Data Gaps: With the primary tool for vital stratospheric water vapor observations set to reach the end of its life, a new data assimilation system (DAS) developed by past and current Global Modeling and Assimilation Office (GMAO) scientists can help fill in future data gaps using other existing sensors. The new GMAO DAS runs at the NASA Center for Climate Simulation (NCCS).

05.29.25 - NASA Enables Detectability Simulations of a Surface Biosignature on a Proxima Centauri b-Like Planet with Future Space Observatories: The NASA Goddard Institute for Space Studies' ROCKE-3D general circulation model, NASA Goddard Space Flight Center's Planetary Spectrum Generator (PSG), and the NASA Scientific Computing Project's high-performance computing resources combined to enable a study exploring the feasibility of searching for signs of life from the surface of a Proxima Centauri b-like planet.

04.25.25 - The Stratospheric Sudden Warming of March 2025 Abruptly Ended the NH Stratospheric Polar Vortex: A cold stratospheric polar region characterized most of the NH winter of 2024-2025, with a major final warming in early March. The NASA Global Modeling and Assimilation Office’s GEOS-FP and GEOS-S2S products were able to forecast and characterize the evolution of this SSW event. GEOS-FP and GEOS-S2S run at the NCCS.

03.25.25 - Critical Simulations of L.A. County Fires Run on NAS Supercomputers: Supercomputers at the NASA Advanced Supercomputing (NAS) facility are used to simulate fire scenarios for a variety of circumstances, such as predicting fire damage in the Vehicle Assembly Building at Kennedy Space Center during a hypothetical ignition of solid rocket boosters. Most recently, scientists from NASA’s Jet Propulsion Laboratory urgently needed our resources and support services to produce very high-resolution simulations of the extreme wind and fire behavior during the January 2025 fires in the Los Angeles area..

03.19.25 - Scientists Simulate the Electrical Dynamics of Thundersnow at NCCS: In a first-of-a-kind study, NASA, university, and industry scientists simulated the electrical dynamics of thundersnow — lightning within snowfall — at the NCCS.

03.14.25 - New Grace Hopper Nodes Double the Power of NASA's Cabeus Supercomputer: As part of the NAS Division’s goal to provide NASA with the computing power needed to support the agency’s missions and programs, 350 NVIDIA Grace Hopper nodes were added to the Cabeus supercomputer, providing more than 13 petaflops of computing power and more than doubling Cabeus’ total peak capability.
